12th Ohio Infantry

The 12th Ohio Infantry was a Union Army regiment which was active from 1861 to 1864 during the American Civil War. It was organized at Cincinnati, Ohio; its first colonel John W. Lowe was killed early in the war at the Battle of Carnifex Ferry in September 1861, so Carr B. White took command. The regiment was attached to the Army of the Potomac and fought at the Second Battle of Bull Run, the Battle of South Mountain, and the Battle of Antietam. It joined David Hunter's 1864 expedition to Lynchburg, Virginia, and it was mustered out of service that same year.
